Rainwater Harvesting: Smarter, Sustainable Water for Your Home

Rainwater harvesting is a simple yet powerful way to take control of your water supply. For homeowners, it can be as basic as collecting water in a barrel for garden use—or as advanced as building a fully off-grid water system. Whatever your goal, planning ahead is key. Many users start small, then expand as they realize the long-term benefits.

Why Harvest Rain Water?

  • Reduce your water bills and reliance on municipal systems

  • Lower residential taxes, like stormwater fees

  • Avoid poor-quality groundwater, including high TDS or contamination

  • Naturally soft water without added softeners

  • Recharge aquifers and reduce environmental impact

  • Conserve precious water, especially during droughts

  • Step 1: Determine Quantity

    Start by calculating your collection potential—based on roof size and average rainfall. Then, consider how you’ll use your harvested water:

    Irrigation & gardens

    Non-potable uses (toilets, laundry)

    Potable uses (drinking, cooking, bathing – with proper treatment)

  • Step 2: Ensure Water Quality

    Rainwater is technically surface water—it can pick up contaminants from the air, roof, and gutters. That’s why filtration and disinfection are crucial:

    First-flush diverters prevent large debris from entering your tank

    Whole-home UV disinfection systems kill bacteria, viruses, and pathogens without chemicals

    Sediment & carbon filters help polish water before UV treatment

Why Choose UV Disinfection?

Ultraviolet (UV) water disinfection is one of the most effective, chemical-free ways to purify rainwater. It uses a specific light wavelength to deactivate microorganisms as water flows through a stainless steel chamber—leaving your water clean and safe.

Low maintenance: Annual lamp change and periodic quartz sleeve cleaning

No taste or chemical residue

Ideal for soft rainwater—no softener required

Choosing the Right UV System

We recommend UV systems from trusted brands like VIQUA, known for high-performance, long-lasting products. Always choose genuine replacement parts and look for certifications from NSF, USEPA, or similar third-party organizations to ensure safety and reliability.
